We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Dave
saying something like:

Absolutely superb. Pity it's only got the one engine, but two engines
might be next.

The clip describes it as 'engines' as in plural.

Typo, or deliberate mis-description.

There is no intake that
could feed one engine, as it would have to be in the middle,

Well hidden. Plus, you only hear one engine start.

also there
is no engine nozzle at the back centre.

Oh, yes there is, underneath.

Look again. It's very very well done, but need two for that total killer
appeal.
